CC   -!- FUNCTION: Catalyzes the formation of UDP-glucose from glucose-1-
CC       phosphate and UTP. This is an intermediate step in the biosynthesis of
CC       diglucosyl-diacylglycerol (Glc2-DAG), i.e. the predominant glycolipid
CC       found in the S.aureus membrane, which is also used as a membrane anchor
CC       for lipoteichoic acid (LTA) (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=alpha-D-glucose 1-phosphate + H(+) + UTP = diphosphate + UDP-
CC         alpha-D-glucose; Xref=Rhea:RHEA:19889, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:33019, ChEBI:CHEBI:46398, ChEBI:CHEBI:58601,
CC         ChEBI:CHEBI:58885; EC=2.7.7.9;
CC   -!- PATHWAY: Glycolipid metabolism; diglucosyl-diacylglycerol biosynthesis.
CC   -!- SIMILARITY: Belongs to the UDPGP type 2 family. {ECO:0000305}.
